Description
Technical field
The present invention relates to a kind of spreading mechanism of oversize, especially a kind of clever chaff is double to shed wheel mechanism, belongs to agriculture machine
Tool technical field.
Background technology
With the continuous improvement of level of agricultural production, the yield of agricultural crop straw is increasing, therefore promotes the comprehensive of stalk
It closes and utilizes, the waste and environmental pollution of resource can not only be reduced, the output level of whole agricultural production system can also be improved, be
Realize the important content of agricultural sustainable development.
In crop threshing course, portion of residual is had --- including a small amount of seed, the plant without threshing and by de-
Stalk more fine crushing drops on sieve plate after grain roller, becomes the oversize of referred to as clever chaff.For a long time, combine harvester pair
The processing of clever chaff be by lip(ped) sieve shake make its discharge after vertical drop to field, be as a result not only due to lip(ped) sieve and shake not
It is enough it is made fully to export, forming accumulation easily on sieve plate influences operation, and drops to field and also inevitably cause part stalk
Accumulation can not efficiently use the nutrient in stalk, can also give field agrarian zone in the future next difficult.
The content of the invention
Present invention aims at：It not only can be with combining in view of the above-mentioned problems of the prior art, proposition is a kind of
Machine is mating, makes the clever chaff of the full and uniform returning to the field of clever chaff is double to shed wheel mechanism, so as to the cropland application for guarantee stalk and field
Operation lays a good foundation.
In order to achieve the above objectives, the double wheel mechanisms of shedding of clever chaff of the invention include level of the interval equipped with two drive bevel gears
Transmission shaft, the crossbeam that the horizontal drive shaft is located above by bearings, the crossbeam equipped with lower end respectively with two actively
Bevel gear forms the left and right vertical shaft of gear pair, and the left and right vertical shaft is respectively provided with left and right spreading board, the spreading board upper surface
Radial ribs outer end be fixed with the flexible board for extending spreading board outer circle, the crossbeam and adjusting of the hinge loaded on horizontal drive shaft
Handle is fixedly connected, the regulation handle with the handle fixed frame being fixed in rack is indexable is fixedly connected.
The flexible board of the present invention stretches out spreading board excircle part will form hypsokinesis curve when spreading board rotates.Therefore it incite somebody to action this
After invention is matched on combine harvester, when sieve, which trembles the clever chaff that wind send, to be fallen on transmission mechanism and drive on the spreading board of rotation,
It will radially throw away under the influence of centrifugal force, and after it leaves spreading board outer circle, the hypsokinesis curve that will be formed along flexible board
It dispenses, so as to uniformly scatter in field, and combine harvester harvesting speed is faster, and the rotating speed of spreading board is higher, flexible board
Hypsokinesis angle it is bigger, dispense it is more uniform.In addition, by the angular position of cover board regulation handle opposite handle fixed frame, it can
To be taken the circumstances into consideration to adjust spreading board and the angle on ground according to the gait of march of combine harvester, so that the clever chaff dispensed out is with required
Uniform distribution falls on earth's surface.

Specific embodiment
Embodiment one
The clever chaff of the present embodiment is double to shed wheel mechanism as shown in Figure 1, 2, 3, and the horizontal drive shaft 7 that belt transmission 30 drives is supported in
On the end plate 33 of both sides, interval is equipped with two drive bevel gears 6 on the horizontal drive shaft 7, and passes through two and be respectively adjacent to corresponding active
The ball bearing 8 and 10 of bevel gear supports the crossbeam 9 being located above.Crossbeam 9 passes through corresponding driven wheel of differential respectively equipped with lower end
27 and two drive bevel gear 6 form gear pair left and right vertical shaft 1.Horizontal drive shaft 7 and the active conical tooth being distributed on the axis
Wheel, ball bearing etc. are respectively positioned in lower encioser 21, therefore avoid interference of the clever chaff of spreading to transmission.Left and right vertical shaft 1 fills respectively
There is left and right spreading board 2, top is fixed with the central cover 17 of taper by stent 16.
Four radial ribs 2-1 are fixed in 2 upper surface of spreading board, and the outer end of each radial ribs 2-1 is fixed with by fastener
Extend the rubber flexible plate 2-2 of 2 outer circle of spreading board.
The fixed left and right case 5,4 being located at respectively outside two spreading boards 2 on crossbeam 9.Structure such as Fig. 4 institutes of case 5 or 4
Show, by having circular arc coaming plate 5-2 outside discount vibram outlet bottom plate 5-1 of the discount vibram outlet bottom plate 5-1, enclosing of middle part notch 5-3 and positioned at circle
The annulus flange 5-4 of arc coaming plate 5-2 top edges is formed.Middle part notch 5-3 and the maximum excircle dimension of central cover 17 match, therefore
Convenient for assembling.Central cover and case, which not only play transmission device, blocks protective action, but also also acts as required clever chaff guiding
Effect.During installation, discount vibram outlet bottom plate 5-1 and circular arc coaming plate 5-2 formed it is open outwardly --- i.e. towards the direction of adjacent end plate,
So that clever chaff is dispensed towards combine harvester both sides.
Crossbeam 9 is fixedly connected with cutting with scissors the regulation handle 11 loaded on horizontal drive shaft 7, and the regulation handle 11 is with passing through bifurcated
Handle fixed frame 12 that arm 12-3 is fixed in rack is indexable to be fixedly connected.Regulation handle 11 and the tool of handle fixed frame 12
Respectively as shown in Figure 5 and Figure 6, handle fixed frame 12 has corresponding fixed with the hinge of 11 one end of regulation handle dress hole 11-1 body structure
There is arc groove 12-2 corresponding with 11 3 location hole 11-2 of regulation handle outside heart hole 12-1, internal point 12-1.Therefore
Fixed mutual angular position can be adjusted on demand, so as to adjust inclining for spreading board and bottom surface on demand by crossbeam indexing
Angle obtains optimal clever chaff and dispenses effect.
Experiment proves that after the mechanism of the present embodiment is provided on combine harvester, power is passed by complete machine by belt wheel
Dynamic driving transmission shaft, and then the spreading board on vertical shaft is driven by bevel gear pair, realize on sieve plate by cleaning fan blow to
The clever chaff of spreading board carries out rotating speed, the uniform of adjustable angle is shed, and effect is very good.
